Abstract

The fresh water resources in Egypt are very limited and almost constant. The
agriculture reuse of drainage water is well developed. The amount of it is expected
to reach 8.8 BCM annually by the year 2017. The objective of the study is to assess
the drainage water to find supplements to the irrigation network at Kalabsho and
Zian Area west of Dakhlia governorate. Drains No.1 and 2 and their branches at
Kalabsho and Zian area are studied here including water quality criteria, extensive
field measurements, constrains and fast interventions, modelling setting and testing
of different scenarios. The comparison between measured field data, calculated data
and the analyzed results indicated that the SOBEK model has a strong adaptability
and can be applied in case of modelling double direction flow which could be used
to simulate the reuse of drainage water. This is very common in Egypt as the canals
could be fed from the head with fresh water and at the tail with drainage water. A
new scheme of water supply management was processed to get advantage of
available drainage water.
